Commercial cleaning

12 questions to ask before hiring a commercial cleaner

Most cleaning companies sound the same on the phone. The difference shows up in the answers to a few specific questions. Ask these before you hire anyone, and you'll know what you're getting.

In short

  • Ask who will actually clean your site, and whether it's the same people each time.
  • Get the scope in writing, with tasks and how often each is done.
  • Check insurance and police checks, and ask how missed tasks are put right.

Questions about the people

  1. Who will actually clean our site? Some companies subcontract the work. That can be fine, but you should know who's coming and who's responsible.
  2. Will it be the same cleaners each time? Regular cleaners learn your site, and standards slip less.
  3. Are your cleaners police checked? For childcare centres and schools, also ask about Working with Children Checks.

Questions about the plan

  1. Can we see the scope in writing? A good answer is a list of areas and tasks, not a paragraph of promises.
  2. How often is each task done? Daily, weekly and monthly tasks should be spelled out.
  3. Who supplies consumables and chemicals? Agree who orders toilet paper, soap and paper towel, and ask which products are used.
  4. What isn't included? Exclusions matter as much as inclusions.

Questions about quality and problems

  1. How do you check the work? Inspections, checklists or photo reports all help.
  2. What happens if something is missed? Look for a clear promise to come back and fix it, at no cost.
  3. How do we contact you, and how fast do you reply? You want one person you can reach.

Questions about the business

  1. What insurance do you hold? At minimum, public liability. Ask for a certificate of currency.
  2. How much notice is needed to change or end the service? You shouldn't be locked into something that isn't working.

How Osso answers these

  • You deal with the owner, and the same cleaners come each time.
  • Everyone who cleans your site holds a current police check.
  • Every client gets a written cleaning plan after a free site visit.
  • Photo reports after each clean, on request.
  • If something's missed, we come back and fix it free.
  • New commercial clients get their first regular clean free, with no obligation to continue.

Questions about this guide

What insurance should a commercial cleaner have?

At minimum, public liability insurance. Ask for a certificate of currency and check that it's current.

Is it a problem if a cleaning company uses subcontractors?

Not always, but you should know who is coming to your site, how they're screened and who is responsible for quality.

What should a cleaning scope include?

The areas, the tasks in each area, how often each task is done, the day and time window, and what's excluded. Our office cleaning checklist is a good template.
